   Originally described as a tagged shaft with a dividing rock bridge. A 5m pitch reaches the floor. Left leads to a choke after 1m, right to a tight rift. Stones bounce for 5 seconds with a couple of seconds free fall but entry to rift is very tight.
   The site was pushed down the tight rift during Easter 2004: A very tight downward squeeze, approximately 3m long, opens out onto the pitch head. Rift opens out into a big shaft, 8 - 10m across. The explorer ran out of rope with another 10 - 15m below. Water can be heard and it "looks very promising".
   This was dropped at Easter 2008 as a p40 with a possible p20 beyond another constriction that requires enlarging.
   The site may have been inspected (from the surface) at Easter 2018.
   See also 0807, 0808, 0809 and 0760.

   The constriction above the second pitch was enlarged in December 2021 and work started to enlarge the tight section at the bottom. "An interesting cave with loads of small parallel shafts which all seem to interconnect or are blind. As previously described, the way on is a calcited 15cm wide, 3m long slot with a big drop on the other side."
